page 48).
Warning!
G
For vehicles equipped with a manual trans-
mission, getting out of your vehicle with the
gearshift lever not engaged in 1st or reverse
gear and parking brake engaged is danger-
ous. Also, when parked on an incline, an en-
gaged 1st or reverse gear alone may not
prevent your vehicle from moving, possibly
hitting people or objects.
Always set the parking brake in addition to
engaging first or reverse gear (
page 56).
When parked on an incline, turn the front
wheel towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay, or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could move the gearshift lever, which could
result in an accident and/or serious injury.Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.
